La revisione del giudicato penale a seguito di pronuncia della Corte europea dei diritti dell’uomo. (II) L’esperienza della Repubblica federale tedes…
2006
Il problema riguardante l'esecuzione delle sentenze di condanna pronunciate dalla Corte europea viene sentito con urgenza in numerosi Paesi. In Italia è stato sinora considerato nell'ambito di diverse iniziative di riforma, ma rimane tuttora aperto. Le riforme introdotte in altri ordinamenti possono offrire utili spunti de iure condendo. In particolare, il contributo si sofferma sulle soluzioni adottate in Germania, dove il legislatore ha previsto un'apposita disposizione che consente la revisione del processo giudicato "iniquo" dalla Corte di Strasburgo: una disamina del quadro normativo e giurisprudenziale di conseguenza determinatosi consente di individuare, oltre ai pregi della riforma,…
Generic revision of Cypricercinae McKenzie, 1971 (Crustacea, Ostracoda), with the description of three new genera and one new species and a phylogene…
2009
The Cypricercinae are one of the most speciose subfamilies of non-marine ostracods, with more than 170 described species, mostly from the tropics. Although the identity of the subfamily as such is clear, because of the presence of unifying characters such as the Triebel’s loop in the attachment of the caudal ramus, the supra-specific taxonomy of this group has long been confused because of lack of good generic and tribal characters. Here, the generic characters of the Cypricercinae are revised. Eleven genera are retained in this subfamily, including three new genera: Bradleytriebella n. gen., Nealecypris n. gen. and Pseudostrandesia n. gen. Tanycypris siamensis n. sp. is described from Thai…
Conditional Random Quantities and Compounds of Conditionals
2013
In this paper we consider finite conditional random quantities and conditional previsions assessments in the setting of coherence. We use a suitable representation for conditional random quantities; in particular the indicator of a conditional event $E|H$ is looked at as a three-valued quantity with values 1, or 0, or $p$, where $p$ is the probability of $E|H$. We introduce a notion of iterated conditional random quantity of the form $(X|H)|K$ defined as a suitable conditional random quantity, which coincides with $X|HK$ when $H \subseteq K$. Based on a recent paper by S. Kaufmann, we introduce a notion of conjunction of two conditional events and then we analyze it in the setting of cohere…
Compound conditionals, Fr\'echet-Hoeffding bounds, and Frank t-norms
2021
Abstract In this paper we consider compound conditionals, Frechet-Hoeffding bounds and the probabilistic interpretation of Frank t-norms. By studying the solvability of suitable linear systems, we show under logical independence the sharpness of the Frechet-Hoeffding bounds for the prevision of conjunctions and disjunctions of n conditional events. In addition, we illustrate some details in the case of three conditional events. We study the set of all coherent prevision assessments on a family containing n conditional events and their conjunction, by verifying that it is convex. We discuss the case where the prevision of conjunctions is assessed by Lukasiewicz t-norms and we give explicit s…
Generalized probabilistic modus ponens
2017
Modus ponens (from A and “if A then C” infer C) is one of the most basic inference rules. The probabilistic modus ponens allows for managing uncertainty by transmitting assigned uncertainties from the premises to the conclusion (i.e., from P(A) and P(C|A) infer P(C)). In this paper, we generalize the probabilistic modus ponens by replacing A by the conditional event A|H. The resulting inference rule involves iterated conditionals (formalized by conditional random quantities) and propagates previsions from the premises to the conclusion. Interestingly, the propagation rules for the lower and the upper bounds on the conclusion of the generalized probabilistic modus ponens coincide with the re…
Conditional Random Quantities and Iterated Conditioning in the Setting of Coherence
2013
We consider conditional random quantities (c.r.q.’s) in the setting of coherence. Given a numerical r.q. X and a non impossible event H, based on betting scheme we represent the c.r.q. X|H as the unconditional r.q. XH + μH c , where μ is the prevision assessed for X|H. We develop some elements for an algebra of c.r.q.’s, by giving a condition under which two c.r.q.’s X|H and Y|K coincide. We show that X|HK coincides with a suitable c.r.q. Y|K and we apply this representation to Bayesian updating of probabilities, by also deepening some aspects of Bayes’ formula. Then, we introduce a notion of iterated c.r.q. (X|H)|K, by analyzing its relationship with X|HK. Our notion of iterated conditiona…
Proposer des révisions intersessions aux étudiants de 1ère année : quelles relations avec la réussite aux examens ?
2013
This paper assesses a revision programme proposed to unsuccessful students between the two examination sessions within the framework of the "Plan réussite en Licence" in first year at the University of Burgundy, both in terms of student participation and links with achievement. The low participation of students is not associated with particular student profiles. An analysis of the students' future shows that student participation in the revision programme led to a lower drop-out risk during the second examination session and greater success, but only as regards the examinations of the 2nd semester. It should also be noted that student participation also has positive effects in the mid-term …
La producción científica sobre distribución comercial en España, 1990-2000

Este trabajo presenta una revisión bibliográfica de la investigación académica sobre distribución comercial publicada en España en el horizonte temporal de 1990 a 2000. Tras una revisión de los trabajos sobre el estado de la cuestión de la investigación en marketing, y las aportaciones más específicas en el campo de la distribución comercial, presentamos la metodología y los principales resultados de la revisión de un número de trabajos procedentes de las publicaciones más relevantes en el campo del marketing. Se extraen conclusiones sobre el carácter científico de los trabajos, los grupos de investigación, la metodología empleada y el contenido de los trabajos y, finalmente, se proponen lí…
Generalized Logical Operations among Conditional Events
2018
We generalize, by a progressive procedure, the notions of conjunction and disjunction of two conditional events to the case of n conditional events. In our coherence-based approach, conjunctions and disjunctions are suitable conditional random quantities. We define the notion of negation, by verifying De Morgan’s Laws. We also show that conjunction and disjunction satisfy the associative and commutative properties, and a monotonicity property. Then, we give some results on coherence of prevision assessments for some families of compounded conditionals; in particular we examine the Frechet-Hoeffding bounds. Moreover, we study the reverse probabilistic inference from the conjunction $\mathcal…
